You are pulling your sister on a sled to the top of a 20.0 m high, frictionless hill with a 10.0o incline. Your sister and the sled have a total mass of 50.0 kg. You pull the sled, starting from rest, with a constant force of 127 N at an angle of 45.0o to the hill. If you pull from the bottom to the top, what will the speed of the sled be when you reach the top?
